5V 5A switching regulator for digital by LM2678
Power supply
Here is circuit switching regulator 5V 5A for digital circuit. Use IC LM2678-5.0 is High Efficiency 5V 5A Step-Down Voltage Regulator This is good power supply, small size and do not hot. Friends want to build the digital power supply which this circuit “Top Linear power supply regulator 5V 5A with 7812 and LM723” is good quality, but as the too old circuit. Not suitable for this era. So I to find a new and very powerful also an Energy savings. Considering these reasons. We will Using an ICs Switching supply. Because of has very high performance. High energy, while …
0-30V 5A variable benchtop power supply using LM723,CA3140,2N3055
Mini Projects
This is 0-30V 5A variable benchtop power supply circuit,Output voltage 0-30V and Current 5A max. Use IC LM723 is a voltage regulator designed primarily for series regulator applications. By itself, it will supply output currents up to 150 mA I so use Transistor 2N3055 X 2 for Booster current to 5A. IC CA3140 for Control Current and Voltage. – P1-50K for control current. – R20-50K for Adjustable voltage output. – R19-5K for fine Adjustable voltage output. – Transformer use 5-8A, Voltage see in circuit. – Detail more see circuit   PCB Variable Regulator 0-30V 5A Parts you will needs IC1…..UA723 …
Top Linear power supply regulator 5V 5A  with 7812 and LM723
Power supply
This ciruit Top Linear power supply 5V voltage regulator 5A. It is good power supply circuit than IC 7805+MJ2955( regulator 5V 5A ) . Use IC 7812 and LM723 regulator IC, Thansistor TIP142 for boost current to 8A max. P1 for Control Volt output 2.5-7V,Transformer 10A min. Detail other see in picture citcuit. When you need a power supply often missed the 3 legs Regulator ICs. But some jobs that apply a high current over 1 Ampere up there, is very difficult. Even if it is 5 amp and 10 amp, but the price is quite high. See circuit and …
